My comment is...

You guys need to make it so that we can share dirty trucks as well as clean ones

I have an older and not all that clean truck, it isn't all that dirty either, but unless the thing is filthy you should be able to share a used not so clean truck for hauling things. I'm not going to try to keep this thing spotless unless people were actually renting it often.

Agreed. Keeping a car spotless, for hourly rentals, will be unprofitable. It costs $20 to clean a truck at the car wash. And sometimes, a 2 hour rental will net only $20. So yes, the option to have dust on the paint or dirt in the bed seems reasonable. Especially if the renter plans on getting it somewhat dirty too. That's what trucks are for.
